Front Thorax Airbag Crash Sensors (Pressure Sensors) Safety Precautions

The thorax airbag crash sensors react to changes in pressure and therefore must be handled very carefully. Note the following points:

• Always pay attention to the correct installation position and only install at the specified component location in the doors.
• Protect the crash sensor from bumps and impacts. Do not use a crash sensor if it has fallen on the floor. When doing body work on the door, the crash sensor should be removed.
• The crash sensor is calibrated to the volume of air inside the door. If the door is deformed resulting in a reduced air space inside the door, the function of the crash sensor will be impaired.
• Avoid contamination of the crash sensor. Do not use compressed air in the area surrounding the crash sensor. Protect crash sensor from filings or shavings (for example, when installing door speakers later). Do not use cavity sealant or spray lubricant near the crash sensor.
• Protect against heat and cold. Avoid heating, for example when painting or doing other body work. Crash sensors should not be subjected to temperatures below -40 °C (-40 °F) (for example, in non-climate-controlled airplane cargo holds).
• Protect the crash sensor from moisture when storing or installing it.

For proper crash sensor function, it must be ensured that the door is sealed properly after assembly. Note the following points:

• All components (such as the cover, speaker, door trim panel) must be installed correctly.
• The door trim panel clips seal the system. Replace the clips if necessary.
